Description

Technical Field

[0001] The utility model relates to the technical field of steel structure trusses, in particular to an integrated green building steel structure truss. Background Technique

[0002] The steel structure truss is a common steel structure form, which is widely used in industrial and civil buildings, bridges, towers and other fields. It is usually composed of multiple planar trusses or space trusses, with good load-bearing capacity and high stability. The steel structure truss can form a single-layer or multi-layer structure system according to different design requirements and is suitable for the support structure of large-span and high-rise buildings. However, for most steel structure truss devices, I-beams or H-beams are used for the cross beams. For the fixation between the cross beams, it is necessary to drill holes in the steel and then use threaded connectors for connection and fixation. Drilling holes in the structural steel may change the mechanical properties of the steel at the drilling positions, thereby affecting the load-bearing capacity of the steel structure truss. Content of the Utility Model

[0003] In order to overcome the problems of most steel structure truss devices, where I-beams or H-beams are used for the cross beams, and for the fixation between the cross beams, it is necessary to drill holes in the steel and then use threaded connectors for connection and fixation. Drilling holes in the structural steel may change the mechanical effects of the steel at the drilling positions, thereby affecting the mechanical properties of the steel structure truss.

[0007] Preferably, a limiting protrusion edge is arranged on the outer side of the first fixing seat, and the cross-section inside the limiting protrusion edge matches the cross-section of the second fixing seat; the docking of the first fixing seat and the second fixing seat is facilitated by the limiting protrusion edge to align the reserved hole positions.

[0008] Preferably, the truss assembly includes a crossbeam and a frame beam; a crossbeam is arranged above the second fixed seat, and a frame beam is arranged on one side of the crossbeam; the truss structure is formed by the crossbeam and the frame beam.

[0009] Preferably, the connecting assembly includes a first fixed block, a first connecting block, a second fixed block, a second connecting block and a connecting threaded connector; a first fixed block is provided on the inner side of the crossbeam, a first connecting block is provided on the outer side of the crossbeam, a second fixed block is provided on the inner side of the frame beam, a second connecting block is provided on the outer side of the frame beam, and a connecting threaded connector is provided on one side of the second connecting block; the crossbeam is fixed by the first fixed block and the first connecting block, the frame beam is fixed by the second fixed block and the second connecting block, and the various parts of the assembly are connected by connecting threaded connectors.

[0010] Preferably, the base assembly includes a pedestal seat, a base bolt and a base nut; a pedestal seat is provided at the bottom of the supporting steel, a base nut is provided above the pedestal seat, and a base bolt is provided at the bottom of the pedestal seat; the pedestal seat is fixed to the supporting steel by threaded connection between the base nut and the base bolt embedded in the foundation.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional steel structure truss device, the cross beams use I-beams or H-steels. The fixation between the cross beams requires punching holes in the steel and then using threaded connectors to connect and fix them. Punching holes in the structural steel may change the mechanical properties of the steel at the punching point, thereby affecting the bearing capacity of the steel structure truss. This device uses a mechanical structure to fix the structural steel by adding a connection structure, avoiding punching holes in the steel, ensuring the mechanical properties of the structural steel, and ensuring the bearing capacity of the steel structure truss;

[0014] 2. When connecting structural steel, place two groups of first fixing blocks inside the inner sides of both sides of the cross beam, place two groups of first connecting blocks on the upper and lower sides of the cross beam respectively, connect and fix the first fixing blocks and the first connecting blocks through connecting threaded connectors, and fix the first connecting blocks and the first fixing blocks to the cross beam through friction. Place two groups of second fixing blocks inside the inner sides of both sides of the frame beam, place two groups of second connecting blocks on the upper and lower sides of the cross beam respectively, connect and fix the second fixing blocks and the second connecting blocks through connecting threaded connectors, and fix the second fixing blocks and the second connecting blocks to the cross beam through friction. Then connect the first connecting block and the second connecting block through a connecting threaded connector to connect and fix the cross beam and the frame beam, so as to solve the problem that most steel structure truss devices need to drill holes in the structural steel for fixation, which is likely to affect the mechanical properties of the structural steel.

[0015] 3. When installing the truss, the base bolts are firmly fixed in the foundation. Through the threaded connection between the base nuts and the base bolts, the bearing platform is fixed to the ground. Insert the support steel into the limiting cylinder. After drilling holes at appropriate positions on the support steel, fix the limiting cylinder and the support steel through limiting threaded connectors to restrict the movement of the support steel. The function of the support steel is to resist tensile and compressive forces, rather than the shear resistance of the cross beam and the frame beam, so the influence of drilling holes is relatively small. The reinforcing rib strengthens the limiting ability of the limiting cylinder. Finally, place the second fixing seat into the first fixing seat and fix the first fixing seat and the second fixing seat through fixing threaded connectors. The limiting protruding edge facilitates the docking of the first fixing seat and the second fixing seat to align the reserved hole positions. BRIEF DESCRIPTION OF THE DRAWINGS
